IVIACIHINE FOR PREPARING AND SPINNING WORSTED.

1 SPECIFICATION forming part of Letters Patent No. 765,7' 16, dated July267 1904,

Application filed April 5, 1904:. Serial No. 201,737. (No model.)

T t/f w/l/m'nl fl: 111.11.51/ concern:

Be it known that I, FREDERICK PIERPONT SHAW, residing' at Lowell, in thecounty of Middlesex and State of Massachusetts,have invented certain newand useful Improvements inMachincs for Preparing and Spinning' Worsted,of which the following description, with the accompanying drawings, is aspecification, like numerals on the drawings denoting like parts.

The invention has relation to certain of the adjuncts of the frontdrawing-rolls of drawing mechanism of the type that is employed inmachines for preparing' and spinning worsted and in the like machines.

In particular the invention relates to the means of supporting the lowerfront drawingroll of a drawing mechanism of such type and to the usualiixtures-in the present instance the horn and hook-which are employed inconnection with the front top rolls.

General objects of the invention are to provide an improvedconstruction, arrangement, and combination of the said means andiixtures, to facilitate the use in the mechanism aforesaid of larger andbetter bearings in connection with the lower front drawing-roll than itheretofore has been practicable to employ, to permit thebearing-surfaces at such bearings to be covered in and protected fromaccess of iyings, dust, Sac., and to render the use of roller-bearingsfeasible.

I have illustrated my invention in the accompanying drawings, in which-Figure 1 shows in front elevation portion of a Vdrawing mechanism'havingone embodiment of the invention applied thereto. Fig. 2 is asectionalside elevation thereof, the plane of section being indicated b v thedotted line 2 2, Fig'. 1. Fig. 3, Sheet 2, is a detail view in sectionon the line 2 2, Fig. 1, on a larger scale than Figs. 1 and 2, with thecasing-plates pertaining' to the end of the bearing removed. Fig. 4,Sheet 2, shows in front elevation certain of the parts of Fig. 3 withthe casingplates in position. Figs. 5 and 6, Sheet 2, show in sideelevation and front elevation, respectively, the adjusting-wedge of Fig.3; and

Fig. 7, same sheet, shows the adjusting-screw I of Fig. 3. Figs. 8 and9, Sheet 3, are views showing in sectional side elevation and frontelevation` respectively, portions of a drawing mechanism in which theso-called hook is mounted upon the bearing-stand. Fig. 10, Sheet 1,shows in side elevation a roll-stand of the form employed in practiceheretofore, with the front carrier-stand mounted thereon, theroller-beam being shown in vertical section. Fig'. 11, Sheet 1, showsthe parts of Fig. 10 in front elevation. Fig. 12, Sheet 1, shows thefront end of the saidl roll-stand of Figs.4 10 and 60 11 inpartly-sectional side elevation, the section being' on the plane that isindicated by the dotted line 12 12, Fig. 11.

Having reference to the drawings, the latter show only a small portionof the drawing mechanism of a machine for preparing or spinningworsted,simply enough to indicate clearly the nature and relations ofthe invention itself. A portion of the usual roller-beam of suchmechanism is represented at 2, and at 11 70 is shown one of theroll-stands. As is well understood, a number of roll-stands is employedin the length of the machine in practice. Their forward ends areprovided with feet, as 111, which rest upon and are secured to theroller-beam. Their rear ends are supported by portions of the framework,which are not show-n in the drawings. Rear drawing-rolls are representedat 12 12, Figs. 1 and 2. At 121 in said figures is shown one of the 8Ostands for the said rear drawing-rolls. The said stands are mounted uponthe said rollstands, being applied to the slideways or guideways withwhich the roll-stands are provided and are adjustable in well-known man-S 5 ner along the said slideways or guideways in the direction fromfront to rear in the machine to increase or diminish the distanceseparating the rear drawing-rolls from the front drawing-rolls.

At 122 122, Sac., are shown the usual carrier-rolls, which are locatedintermediate the rear drawing-rolls and the front drawingrolls, and at123 123, te., are shown the carrier-stands supporting the carrier rolls122 95 122, &c., the said carrier-stands being mounted upon theroll-stands in the usual manner with capacity for adjustment along theslide ways or guideways of the said roll-stands in the direction fromfront to rear in the machine. The usual wooden presser-rolls which areapplied in practice to the carrier-rolls for the purpose of holding theslivers or rovings pressed lightly against the latter are omitted fromFig'. 1, but are shown in Figs. 2 and 3 at 129 129, &c. The ends of thesaid presserrolls are applied to guides with which the carrier-standsare furnished. The shaft of the lower front drawing-roll is shown at 3,and the drawing-bosses of the said drawing-roll are represented at 3131, Sac. The said shaft is supported in bearings which are provided uponor adjacent the roll-stands, as referred to hereinafter. rlhe front toprolls which cooperate with the bosses 31 31, &c., consist, as usual, ofbosses 4 4, Sac., which are attached in pairs to short shafts 41 41,&c., the ends of each such short shaft projecting at the opposite sidesof the pair of bosses thereon to constitute journals. The fixed horns socalled, rising adjacent the bosses 31 31, zc., and constituting guidesfor the said journals whereby the working positions of the front toprolls are determined with respect to the lower front drawing-rolls aremarked 5 5, Sac. Intermediate the roll-stands the horns are mounted uponthe roller-beam or other convenient su pport. At the roll-stands thehorns are applied and supported in the manner which presently will beexplained. Each thereof is furnished, as usual, with one or morelaterally-projecting wings 51 51, Figs. 3 and 4, Sheet 2, against therear faces of which the journals of the front top rolls rest, and eachhorn has a longitudinally-extending rib 52. r1`he ribs of the respectivehorns serve as guides for the ends of the journals of the front toprolls. They coact with the said ends to prevent endwise movement of thesaid top rolls, and thereby they fix the position, transverselyconsidered, of the bosses 4 4 of the latter with relation to the bosses31 31, &c., of the front drawing-roll. The said bosses 4 4 are pressedagainst the bosses 31 31 of the lower front drawing-roll by means ofpressure or tension devices of usual character, such devices beingrepresented in Figs. 1, 3, 8, and 9 and comprising for each pair offront top-roll bosses a saddle 6, which bears upon the upper side of theshaft 41 of such pair of bosses intermediate the latter, a stirrup 7having the stem thereof passed through a hole in said saddle and itshook-shaped lower end passed through ahole in the fixed .so-called "hook8 and engaged with the latter, an expanding' spiral spring' 9,surrounding the upper portion of the said stem above the saddle, and athumb-nut 10, screwed upon the threaded upper end of the stirrup. Thehooks 8 usually are mounted upon the saddle-rail 81, as in Fig. 1, orother convenient support; but m certain cases I contemplate mounting apart thereof upon the roll-stands, as will be explained hereinafter. Thesaid spring 9 is compressed between the thumb-nut and the saddle, andits tension is adjusted by means of the said thumb-nut to secure thedesired pressure of the top-roll bosses 4 4 against the bosses 31 31.Pressure or tension devices, in the main similar to those which are usedin connection with the front top rolls, are used with the rear topdrawing-rolls.

Referring now to the roll-stands, the bearings for the shaft 3 of thelower front drawing-roll, the horns, and the hooks, I will eX- plain thenovel construction, Sac., in which the invention resides.

Figs. 10, 11, and 12, Sheet 1, show the construction, arrangement, &c.,of the roll-stand, the bearing for the lower front drawing-roll, and thehorn usually employed heretofore.

In these figures the bearing is marked 132, the seat or socket which isoccupied by the said bearing being marked 131 and the horn being marked53. The front carrier-stand 123 is shown in position upon the slidewayor guideway of the roll-stand. T he bearing 132 is a simple open-toppedbearing or halfboX. The seat or socket 131 is formed in the front end ofthe roll-stand and opens upwardly at right angles to the length of theslideway or guideway of the roll-stand. It is open-topped. The frontwall 133 of the said seat or socket rises above the top of the .frontwall of the bearing directly at the front of the latter; but above thesaid front wall 133, between the -same and the upper portion the horn,there is an unobstructed opening to afford opportunity to insert thebearing or the shaft of the lower front drawing-roll by first moving thesame rearward into a position above and in line with the opening of theseat or socket and then moving it downward in the direction of the saidopening into work ing' position within the seat o1' socket and to removethe said shaft or the bearing by the reverse action. The horn 53 must beso shaped and located that it will not interfere with the insertion andremoval of the lower front drawing-roll and the bearing 132. Hence atthe front it must not extend into the path which is required to be takenby the shaft and bear ing in being inserted or removed. In addition inorder to enable the bite of the front carrier-roll 122 and itspressure-roll 129 to be set as close to the bite of the frontdrawingrolls as possible, as sometimes is required in practice, the hornmust not interfere with adjustment of the front carrierstand far enoughforward upon the roll-stand to give the front carrier-roll 122 and itspressure-roll 129 a position in which the peripherics of the said rollsjust clear the peripherics of the bosses 4 4 31 31 of the frontdrawing-rolls. Hence at the rear thereof the horn mustbe so shaped andlocated as to permit such adjustment to IOO be made. In order to meetthese require-A angles to the length of the slideway or guideway. At thefront thereof the said post is formed with a straight su rface 134,constituting the upper portion of the rear wall of the seat or socket131 and also extending in continuation thereof to a distance from saidseat or socket sufficient to enable the bearing 132 to occupy a positionin line with the seat or socket, but entirely above the upper end of thefront wall 133 of the latter. This straight surface acts as a guide forthe bearing and shaft in being inserted into place or removed therefrom.The rear side of the horn is located in advance of the foremost positionwhich is required to be assumed by the front carrier-stand, and in orderto enable the latter to fit closely up against the horn the said rearside is formed with a hollow 531, which receives theforwardly-projecting convexity 127 of the bearing portion of the saidcarrier-stand. The thickness of the neck or contracted portion 532 ofthe post of the horn, Fig. 12, in the direction from front-to rear mustbe suicient to insure enough material at lthe said neck in front of thehollowv531 to confer strength to obviate liability to breakage at suchneck. Hence inasmuch asthe space at the rear of the journal portion ofthe shaft of the lower front drawing-roll, measuring in the directionfrom front to rear in the machine, which is available to be occupied bythe post of the horn and the portion of the bearing that projectsrearward of the said journal portion is small, and as the proportionthereof that is required to be devoted to securing suiiicient thicknessof the horn at the neck 532 is relatively considerable only a shortdistance intervenes in practice between the straight front surface 134of the post of the horn and the surface of the journal portion toreceive the rear wall of the bearing 132. Therefore the said rear Wallof the said bearing is made quite thin at its upper edge.

- (See Figs. 10 to 12.) In all instances known to me heretofore thebearing 132 invariably has been a plain or simple bearing, and for wantof room, &c., for the convenient application of a cover the said bearinghas been left unprovided with a cover, as in the said figures. Inoperation the portions of the shaft of the lower front drawing-rollwhich work in the bearings become covered with lubricant, and inconsequence4 of the absence of covers dust and iiyingscollect upon suchportions. As a result the lubricant of the bearings become charged withimpurities, which latter clog the bearings and cause cutting' of theshaft and the bearings, as well as occasion other injuries. The cuttingof the shaft by particles of wool which work in between them progressesrapidly and is an extensive and serious cause of trouble.

In accordance with my present invention the bearing seat orsocket isopen to the front directly in advance of the front wall of the bearingwhich occupies the same, as contradistinguished from a bearing seat orsocket which is merely open-topped, as heretofore. Iith my improvedconstruction the bearing and the journal of the lower front drawingrollwhich lits therein are inserted into the said bearing seat or socket andare removed therefrom at the front of the bearing seat or socket insteadof the top thereof, as heretofore. A bearing seat or socket embodyingthe invention-4,'. e., open to the front in advance of the front wall ofthe bearing and not merely open at the top above the said bearingisshown at 133, Fig. 3, at the front end of the roll-stand. In the case ofa construction in which the bearing seat or socket is formed to permitthe bearing and the lower front drawing-roll to be inserted and removedby movement from front to rear, as in Fig. 3,

instead of by movement downward or upward, as in the usual construction,(shown in Figs. 1() to 12, it is unnecessary to have an unobstructedopening above the bearing seat or socket, and it is not required thatthe supporting portion of the horn or other top-roll fixture should beformed as a post having a straight front surface 134 extended upward inva straight line in continuation of the rear wall of the bearing seat orsocket. Consequently I am enabled to enlarge the bearing seat or socketat the rear thereof so as to extend more or less beneath the base orsupporting portion of the horn or other top-roll fixture, therebvenabling a largerl and better bearing, which may be a roller-bearing, tobe employed, and the said base or supporting portion of the lhorn mayoverhang the bearing seat or socket to any desired extent and have theoperative portion of the fixture set farther forward, so as to leave atthe rear thereof ample clear space free to be occupied by the upper oroperative portion of the front carrier-stand. If desired, the portion ofthe base or supporting portion of the fixture which overhangs thebearing seat or socket may be enlarged-to constitute a top for thebearing seat or socket, as at 134 in the drawings, or some otherapproved form of top may be provided. I term the top 134 a fixed top,inasmuch as ordinarilyit is intended to remain in its working positionand not to be removed merely for the purpose of enabling the lowerffrontdrawing-roll and its bearing to be taken out or replaced or for otherlikereasons. In the present instance the top 134is integral with thestand, which is preferable but not indispensable. It projectsforwardlyabove the bearing that occupies the bearing seat or socket inclose proximity to the latter. The operative portion of the horn 5,which is employed at the bearing, rises from this top 134 well forwardupon the front portion of the IIO top 134, so that theupwardly-extending operative portion of the horn shall be entirely clearof all portions of the front carrier-stand in the cxtreme forwardposition of adjustment of thelatter. In consequence of the low positionwhich I am enabled to give the base or supporting portion of thetop-roll fixtureal. a., the top 134, as shown in Fig. 34the upperportion of the front carrier-stand rises above the former, and itsbearing portion is free to project forward over the same, as in the saidfigure. At the place of the connection of the curved rear portion of thebase or supporting portion (top 134) of the top-roll fixture with thestand it is necessary only that such portion should have sufficientthickness to insure strength. The proper strength of the same admits ofbeing secured with considerably less thickness in the direction fromfront to rear in the machine than is employed at the base of the post ofthe horn of the old construction which is represented in Figs. 10, 11,and 1Q. I am therefore enabled to reduce the thickness in the saiddirection at the place mentioned and also to give the said portion aposition rearward closely adjacent the front end of the slideway orguideway of the rollstand. The relatively small thickness of thisportion in the direction from front to rear and the rearward positionoccupied thereby leave considerable more space available in advance ofthe same at the rear of the axis of the lower front drawing-roll for usein connection with the bearing than in the old construction shown inFigs. 10 to 12.

In Fig. 3 I have shown applied to the bearing seat or socket and inconnection with the journal portion of the loivcnfront drawingroll aconvenient construction of roller-bearing, the same comprising,essentially, a series of antifriction-rolls 135 135, Sac., a cage forthe said rolls consisting of annular end pieces 136 (one only beingshown in Fig. 3) and pins 137 137, &c., passing centrally through thesaid antifriction-rolls and engaged at their opposite ends with theannular end pieces 136, a lower half-box 138, upon the concave surfaceof which the antifriction-rolls travel and by which they are sustained,and an upper half-box 139, which is concaved to fit over the upperportion of the series of antifriction-rolls and the correspondingportions of their annular end pieces. In practice I make suitableprovision for securing the bearing in place within the bearing seat orsocket 133. This may be effected in various ways. In the presentinstance I accomplish said result and at the same time close the openingat the front of the bearing seat or socket, so as to exclude dust,flyings, and the like, by means of a removable cover-plate 140, which isheld in place by means of screws 141 141, &c. The inner side of the saidcover makes contact with the forward ends of the half-boxes 138 139, andthereby the cover holds the'latter from displacement forwardly. The twohalfboxes are confined and clamped between the said cover and the innerend of the bearing seat or socket. The fixed top 134 serves to cover thebearing above. It will be perceived that when such fixed top is anintegral portion of the roll-stand, as in Fig. 3, it constitutes a coverthat requires no fastenings at the rear of the axis of the lower frontdrawing-roll to occupy space. The extent to which the top 134 projectsforward above the bearing, as well as its form and dimensions, as wellas those of the cover-plate 140, and the manner and means of effectingthe attachment of the cover-plate, may vary in practice. For the purposeof closing the opposite ends of the bearing against the admission ofdust, flyings, &c., I employ the upper and lower casing-plates 142 143,(shown best in Figs. 2, 8, and 9,) which are fastened in place by meansof screws 144 144, Sac., Fig. 8, the stems of the said screws enteringthreaded holes 145 145, &c., Fig. 3, which are tapped in the oppositeends of the halfboxes 138 139. The casing-plates meet at front and rearof the shaft 3 of the lower front drawing-roll, as shown in Figs. 2 and8, and are concaved to fit closely around the said shaft. For thepurpose of providing for vertical adjustment of the bearing within thebearing seat or socket any usual or preferred means may be employed. Ihave herein shown aconvenient means of adjustment comprisinga wedge 146,Figs. 3, 5, and 6, and an adjusting-screw 147, Figs. 3, 4, and 7. Thewedge 146 is introduced between the under side of the half-box 138 andthe bottom of the bearing seat or socket 133. The lower surfaceA of thewedge is formed at aslight angle with reference to the upper surfacethereof. The said upper surface fits against the under side of thehalf-box 138, while the inclined lower surface of the wedge fits againstthe correspondingly-inclined bottom of the bearing seat or socket. Atits outer end the wedge is formed with a pair of lugs 148 148, and thescrew 146 is reduced in diameter near its inner end, forming a neck 149,Fig. 7. The said neck of the screw is fitted between the lugs 148 148.Vhen the screw is turned in the threaded hole which is tapped throughthe lower part of the cover-plate 14() and within which the said screwis fitted, the engagement of the shoulders which exist at the oppositesides of the said neck 149 with the lugs 148 148 causes the wedge 146 tobe moved endwise in order thereby to either raise the bearing or lowerthe same. In this manner the bearing may be adjusted in the directionand to the extent which may be required in alining the said bearing withthe others which are employed in connection with the lower frontdrawing-roll. It is not intended in the present instance that the rolls135 135 shall make contact with the under surface of the upper half-box139, and accordingly the concavity IOO IIO

of the said upper half-box is formed with a radius slightly greater thanthat of the curved path along which the outer portions of theantifriction-rolls travel. 14 14 are set-screws which are fitted tothreaded holes that are tapped through the fixed top 134 and bear it attheir lower ends against the top of the said upper half-box 139. Thesaid upper half-box intervenes between the said set-screws and the lowerhalf-box 138 and serves to hold or clamp the latter down to place bytransmitting pressure to the same from the set-screws 14 14. The saidupper half-box may be dispensed with in many cases, in which event thescrews 14.14, or the equivalent thereof, if employed, may be arranged tocoact directly with the half-box 138.

Preferably the horn 5 is formed as a separate piece and is detachablysecured, by means of a screw 54, to the fixed top 134. The detachabilityof the horn enables it to be removed whenever worn or injured and a newone to be substituted therefor without it being necessary to replace theentire stand, as heretofore required in the like case. In order toprovide for making an angular shift of the front top rolls with respectto the axis of the lower front drawing-roll whenever such shift may berequired for the attainment of the best results in practice, thedetachable horn is made adjustable upon the fixed top 134 in thedirection from front to rear in the machine. To this end the opening 55in the foot or base of the horn 5, through which the securing-screw 54passes, is made in the form of a slot that is elongated in the saiddirection, and the foot or base of the'horn is fitted to the fixed top134 in a manner enabling the horn to be shifted forwardly or rearwardlyupon the top when the said securing-screw 54 is loosened. In order toprevent turning or twisting of the horn upon the fixed top 134, theupper side -of the top 134 and the foot or base of the horn are formedwith interlocking ribs and grooves,`as shown best in Fig. 4, whichpermit the shift aforesaid while operating to prevent lateral movementof the horn.

I have shown the bearing seat or socket 133 as formed in the front endof the roll-stand 11; but it is not necessary to my invention that thesaid bearing seat or socket should be formed in an integral portion of aroll-stand. It may be formed instead in a separate stand, as will beobvious. F or 'the purpose of this case, therefore, the stand whichcontains the bearing seat or socket may be regarded as a bearing-stand,and I have thus designated the same in the claims where I seek todistinguish the same broadly from the roll-stand per se.

To a certain extent the horns 5 and the hooks 8 are interchangeable inposition with relation to the bearing-stands. In other words, in casesin which it is desired that the top rolls, hhorns, hooks, and tension orpressure devices shall be so arranged as to cause the said tension orpressure devices to act in line vertically with the bearingas, forinstance, in my application for United States Letters Patent forimprovements in machines for preparing and spinning worsted, filed April5, 1904, Serial No. 201,736-a hook 8 may be mounted upon the fixed top134 of a bearingstand, as shown in Figs. 8 and 9, in which thearrangement is otherwise essentially the same as in Figs. 3 and 4. Myinvention in its broader phase will be embodied equally in the case ofFigs. 8 and 9, for, as will be perceived,

the essential principles of the same are contained in the constructionwhich` is shown in the latter figures. For this reason, therefore, Idesignate both the horn and the hook as top-roll fixtures, and by theterm toproll fixture as employed in certain of the claims I contemplateas well a hook as a horn for the purposes of such claims.
